DISINFECTING APPARATUS.

Specification of Letters Patent.

Patented Sept. 3, 1907.

Application filed August 21,1905. Serial No. 276.105.

To all whom it may concern.-

Be it known that I, WILLIAM H. Rosn, a citizen of Figure .l is a view of a closet bowl with one form of disinfecting apparatus applied thereto; Fig. 2 is a sectional view' of the pump shown in Fig. 1, and Fig. 3 is a sectional view of another form of disinfectant pump embodying the invention.

1n the drawing 1 have shown two forms of apparatus, one being a pump for fluid disinfectant only and the other being a combined fluid and air pump. I shall first describe the'lluid pump which is the same in both cases.

Referring to the drawing, 1 indicates a closet bowl or other vessel to be disinfected, and 2 a receptacle for disinfectant, the said recepti'tcle being suitably con- Ilccted to the wall adjoining the closet. In the lower part of the vessel 2 is arranged a punip cylinder 3 having a bore of small diameter and comparatively long, the cylinder being suitably proportioned to hold the amount of disinfectant required for a single charge. The delivery tube 4 extends from the bottom of the cylinder to the discharge point 5, (Fig. 3) or into the closet I, as may be desired. The cylinder 3 fills through a small perforation 6. It is intended that the cylinder shall fill slowly to prevent the disinfectant being wasted. \\hen the pump piston 7 is pushed down after the cylinder is full, the contents of the cyl- 'inder will be discharged. If the piston be drawn up and immediately pushed down again, but little disinfectant will be discharged on'account oi the limited supply through the opening 6. The piston 7 is normally sustained in an elevated position by means of a spring 8, and a perforation 9 is located at the upper end of the cylinder to permit the piston to rise above the opening (5. It will be seen that as the piston moves down i I. will expel a portion-Of the fluid through the opening (5, until it reaches the opening. Communication between the cylinder and the disinfectant in the,

vessel 2 will then be cut off and the fluid in the cylinder below the opening 6 will be forced positively through the tube 4. A small opening 10 is provided in the upper part of the tube 4 (Fig. 2) to prevent the fluid from siphoning over after the pumphas operated, and also to prevent the charge of disinfectant in the discharge end of the tube 4 from being drawn back into the pump, and to permit the pump piston to move freely upward, whereby the piston may be operated by a light spring.

In that form of the invention illustrated in Fig. 3, the fluid .pump is the same as above described. The delivery pipe leads to the atomizing point 5 however and there is an air pump which delivers air at the same point, which pump will. now be described.

In or upon the upper part of the essel 2 (Fig. 3) is an air pump comprising a cylinder 11 and a suitable piston 12. The pistons 7 and 12 are operated simultaneously and they are preferably fixed to the same piston rod 13, which rod extends above the cylinder 11 and is provided with a suitable knob or handle 14. An air tube 15 extends from the bottom ofthe cylinder 11 I and discharges at the point 5 atomizing the fluid which is simultaneously delivered from the pipe 4 at the point 5.

It will be seen that my improved apparatus, as shown in Fig. 3, delivers disinfecting fluid in 1neasured quantities and atomizcs the same at the point of delivery, and that furthermore, it is so constructed that wasteful use of the disinfectant is prevented.

The apparatus is preferably constructed and used as illustrated but it will be evident thatit may be en1-' bodied .in many different forms.

The atomizer shown in Fig. 3'may be used to spray disinfectant into the atmosphere, while the pump shown in Figs. 1 and 2 is especially adapted for closets and urinals.

In Fig. 3 I have also shown a fluid delivery pipe 4 which may lead to a closet bowl as in Fig. 1.. When the two fluid discharge pipes are used a simultaneous discharge of fluid into the closet or other vessel to be disinfected and into the atmosphere is effected, which is very desirable under some conditions.

It will be evident that the pipe .4 may be a branch of the pipe 4 or vice versa, and that it may be omitted, if desired.

i In some cases the two sources of fluid may be used, a volatile or aromatic fluid for the atomizerheavier fluid for disinfecting purposes. In such case the pump 3 may be used for the disinfecting fluid alone, and the atomizer supply pipe 4 may communicate with thede-odorizing fluid receptacle, the atomizer operating in the usual way to draw up the fluid" 100 without the aid of a pump.

Having described my invention What I claim as new and desire to secure by Letters Patent, is

1. In a disinfecting apparatus, the combination of a receptacle for disinfectant, a pump in said receptacle having 105 an upper: inlet and a lower outlet opening, a piston, a spring for normally holding the piston above the inlet opening, means for operating the piston, and a deliverytube connected with the outlet opening and leading to a and a level higher than the fluid in the receptacle and provided with a perforation above the level of the fluid to' prevent siphoning, snid perforation being arranged to discharge into the said receptacle.

2. In a disinfecting apparatus, the combination of a pump for measuring and delivering fixed quantities of disinfectani', an air pump having a discharge arranged to n tomize the disinfectant, and means for simultaneously operating said pumps.

3. In a disinfecting apparatus, the combination with a vessel for disinfectant, ot-a fluid pump and an air pump connected to sald vessel and n common piston rod for said pumps. i,

4. Ina disinfecting apparatus, the combination with a receptacle for disinfectant, o; a fluid pump of i elntlveiy small diameter, an air pump of relatively large diameter, i1

common piston rod, and delivery pipes extending from said pumps to a common point, and constituting an atomizer.

5. in a disinfecting apparatus, the combination with a receptacle for disinfectant, of a fluid pump, an air pump, delivery pipes leading from said pumps to a common point and constituting an atomizer, and a second delivery pipe connected with the fluid pump and adapted to deliver fluid simultaneously with the operation of the atomizer.

in testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
